Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to a mesothelioma effusion drainage device. Background Art

[0002] Pleural mesothelioma is a primary tumor derived from pleural mesothelial cells, accounting for 5% of pleural tumors, and is clinically rare. Pleural mesothelioma can occur in any part of the visceral pleura and parietal pleura, 80% of which occur in the visceral pleura and 20% in the parietal pleura; it can occur at any age, but is common in 40 to 60 years old. Both mesothelioma and extensive pleural metastases can cause extensive irregular or nodular thickening of the pleura with pleural effusion, and a drainage device is required to drain the effusion in the pleural cavity during treatment.

[0003] First, the existing fluid drainage device requires the user to tightly clamp one end of the drainage tube with a medical clamp before and after puncture to prevent the accumulated fluid from flowing out when the syringe is not connected. However, the clamp requires the user to clamp it firmly all the time, which is time-consuming and labor-intensive, reducing the practicality of the device.

[0004] Second, the existing drainage device requires the user to pull the pull rod on the syringe when extracting the accumulated fluid. However, since the inner diameter of the needle inserted into the chest cavity is small, the user needs to spend a lot of effort and too much time to complete the extraction of the accumulated fluid, and the extraction efficiency is low.

[0007] Preferably, a limiting ring is welded on the bottom of the driven gear, the limiting ring is movably engaged with the top of the liquid collection tube, and the bottom of the connecting plate is bolted to the top of the liquid collection tube.

[0008] Preferably, a driving rod passes through the driving gear, the driving rod is bolted to the output end of the rotating motor, and the rotating motor is bolted to the inside of the fixed shell.

[0009] Preferably, a snap ring is adhered to one side of the connecting plate close to the fixed shell, a snap groove is formed on the outside of the fixed shell, and the snap ring is movably engaged in the snap groove.

[0010] Preferably, a movable rod is movably penetrated through one side of the movable block, and one end of the movable rod close to the drainage tube is bolted to a support block, and the edges at both ends of the support block are respectively against the surfaces of the two adapter plates.

[0011] Preferably, a side of the adapter plate away from the support block movably penetrates a limit rod, an elastic member surrounds the limit rod, and two ends of the elastic member are respectively bolted to the sides of the two adapter plates close to each other.

[0013] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0014] First, a movable block is sleeved on the outside of the drainage tube and moved to an appropriate position, and then the movable rod is pulled outward so that the support block is squeezed out from between the two adapter plates when moving. Since the support block is trapezoidal, the two adapter plates are no longer subjected to thrust, and the elastic parts are elastically moved closer to each other, so that the splint clamps the drainage tube and seals it. At this time, the needle is inserted into the position where the patient needs to extract the accumulated fluid, and the support block is pushed between the two adapter plates again to connect the drainage tube with the accumulation fluid tube. Multiple components cooperate with each other to quickly seal the drainage tube, reducing the number of steps for operators to clamp the drainage tube with pliers, saving time and effort, and improving the practicability of the device.

[0015] Second, place the fixed shell between the connecting plate and the driven gear so that the retaining ring is embedded in the retaining groove. At this time, the fixed shell is fixed on the top of the liquid accumulation tube. Turn on the rotating motor to drive the driving gear to rotate, and then the driven gear to rotate. The threaded rod will rise when the driven gear rotates, driving the lifting block to gradually rise. The change in air pressure will draw the accumulated liquid into the liquid accumulation tube through the drainage tube to complete the drainage of the accumulated liquid. Using a rotating motor to drive the lifting block to move and extract the accumulated liquid can reduce manpower output, thereby improving the extraction efficiency. The detachable fixed shell can be reused, reducing the use cost of the device. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the needle 3 is inserted into the position where the patient needs to extract the accumulated fluid, and then the support block 19 is pushed back between the two adapter plates 20 to connect the drainage tube 2 with the fluid collection tube 1. Multiple components cooperate with each other to quickly seal the drainage tube 2, reducing the number of steps for the operator to clamp the drainage tube 2 with pliers, saving time and effort, and improving the practicability of the device.
